Chelsea Baker has been recognized by the National Baseball Hall of Fame for doing something extraordinary.

The 13-year-old female has pitched not one, but two perfect games, against boys.

Chelsea recently donated the jersey she wore to pitch one of those perfect games to the Hall of Fame in Cooperstown, New York. The jersey will be featured in an exhibit on the importance of women in baseball.

Baker has been pitching since she was 7 years old. Her arsenal contains a fastball around 65 m.p.h. and an astounding knuckleball that confuses opponents.

“Yeah, when I strike them out with the knuckleball, sometimes they’ll throw their helmets and start crying,” she says. “It’s just really funny to watch.”

It’s a pitch she learned from pitcher Joe Niekro, who was her team’s batting pitcher before he died back in 2006.

“He would always throw it to us and I could never hit it, and so I’d always beg him to teach it to me and finally one day he just taught it to me,” she says.
